Regular and Chaotic Motion in Hamiltonian Systems
All laws that describe the time evolution of a continuous system are given in the form of differential equations, ordinary (if the law involves one...

Algorithmic Challenges in Structural Molecular Biology and Proteomics
This paper reviews our research in computational biology and chemistry. Some of the most challenging and influential opportunities for Physical...

Automatic Generation of Camera Motion to Track a Moving Guide
Manually following a moving object through a cluttered virtual environment can be challenging for the user. Instead, one would typically rather focus...

Adaptive RRTs for Validating Hybrid Robotic Control Systems
Most robot control and planning algorithms are complex, involving a combination of reactive controllers, behavior-based controllers, and deliberative...
-
Applications of the Cluster Statistics
This chapter presents a conceptually straightforward treatment of spatial correlations of “random” heterogeneous media, but does not intend to...

Porous Media Primer for Physicists
During the 1980's physicists (and some geophysicists) devoted considerable efforts to understanding the physical (meaning here not hydraulic)...

Online Searching with an Autonomous Robot
We discuss online strategies for visibility-based searching for an object hidden behind a corner, using Kurt3D, a real autonomous mobile robot. This...

A Machine Learning Approach for Feature-Sensitive Motion Planning
Although there are many motion planning techniques, there is no method that outperforms all others for all problem instances. Rather, each technique...

Locating and Capturing an Evader in a Polygonal Environment
This paper contains two main results: First, we revisit the well-known visibility based pursuit-evasion problem and show that, in contrast to...

Multi-Step Motion Planning for Free-Climbing Robots
This paper studies non-gaited, multi-step motion planning, to enable limbed robots to free-climb vertical rock. The application of a multi-step...

Composing Navigation Functions on Cartesian Products of Manifolds with Boundary
Given two compact, simply connected manifolds with boundary, and a navigation function (NF) on each manifold, this paper presents a simple...

A Simple Algorithm for Complete Motion Planning of Translating Polyhedral Robots
We present an algorithm for complete path planning for translating polyhedral robots in 3D. Instead of exactly computing an explicit representation...

Modeling Macromolecular Machines Using Rigid-Cluster Networks
Many macromolecules consist of domains which act more or less as rigid bodies during large conformational changes. These collective motions are...

Percolation Theory
Percolation describes properties related to the connectivity of large numbers of objects which individually have some spatial extent, and for which...

Heterogeneous changes in global glacial lakes under coupled climate warming and glacier thinning
Global glacial lakes have expanded markedly in recent decades, accompanied by many catastrophic glacial lake outburst floods. However, our...

Geotechnical characterisation and 2D soil cross-section model development in the Kashmir Basin
An integrated analysis of the surface geology with geotechnical parameters of soils within the Kashmir Basin has been presented in this study....

Estimating S-wave amplitude for earthquake early warning in New Zealand: Leveraging the first 3 seconds of P-Wave
This study addresses the critical question of predicting the amplitude of S-waves during earthquakes in Aotearoa New Zealand (NZ), a highly...

Forecasting short- and medium-term streamflow using stacked ensemble models and different meta-learners
Streamflow forecasting holds a pivotal role in the effective management of water resources, flood control, hydropower generation, agricultural...

Using Sentinel-5P TROPOMI Data for Air Quality Assessment in the City of Oran, Western Algeria
With economic development, the emergence of cities, and the growth of transportation, air quality has become a significant concern. This leads to...
